OBTAIN: The Occurrence of Bleeding and Thrombosis during Antiplatelet therapy In Non-cardiac surgery Study

About OBTAIN

The OBTAIN study will examine the risks and benefits of continuing antiplatelet treatment in patients presenting for non-cardiac surgery who have one or more coronary artery stents in situ. The risks of perioperative major adverse cardiac events (MACE) in patients who discontinue antiplatelet drugs will be compared with the risk of intraoperative and postoperative bleeding in patients who continue these drugs.
